KATSU Dial Test Indicator Gauge 0-10mm, 0.01mm Accuracy Metric Travel Machinist's Dial Indicator Measuring Meter High Precision Instrument Tool 401120

I have a few of these now and they work absolutely fine.

cheap and cheerful dial indicator - works well and is as accurate as its specs - a tiny bit of light oil on the bezel and it improves really well - i might have been lucky and got the best one ever made!!!! a lot of other buyers mention hands falling off and non turning grating bezels but mine is jst fine!!

I bought the 10mm dial indicator because I don't need any more range. I suspect this is made for a US market because the useable range is 13+ mm e.g. 1/2 inch. The action is smooth and repeatable, with a spring force that's about right. The back is plastic and there are four screws so it's possible to rotate the mounting hole 90 degrees if required. The top is slightly domed so the plastic "glass" is slightly proud of the front at the centre. The dial rotation is smooth and the main parts are chromed steel for the sliding pin, main housing and clamp. the bezel is also metal. Compared to a pair of digital callipers it is as accurate (0.01mm) or better e.g. measure a steel bar or a metal coin and compare. Especially useful for measuring drift on a saw blade or runout on a drill. With care it could be clamped by the shaft, but I will probably use a bolt through the mounting hole with two metal washers. Comes in a cardboard box with a polystyrene carrier (best kept for protection). Feels like a Swiss watch e.g. delicate but precise and probably more rugged than it looks. Made in China but with a degree of care/precision. With care it should last a lifetime and has a (measured) value much more than it costs. Highly recommended.

Good value dial gauge that seems pretty accurate, but loses a star for the rather stiff zeroing adjustment.

Bought it to use when aligning my table saw.

I am using this gauge to measure the thickness of soundboards for acoustic guitars. The 10mm range is more than enough for my purposes. I chose a dial gauge over a digital gauge so that I could more easily see variations, sliding the board underneath. I modified my shooting board to accept the gauge, and the butterfly nuts at both ends of my clamping board get me to just touching the surface (0.05mm) - the adjustable bezel zeros the reading. The gauge is accurate to within 0.02 mm of my digital vernier calipers, but the most impressive thing is the repeatability of measurements. On removing the soundboard the reading returns to exactly zero - time after time. I am highly impressed with this item and would recommend it, especially since commercial tools for measuring soundboard thickness cost well over £100.
